Nomenclature clay minerals

The name bementite, sometimes used for the former mineral, has priority for a Mn-rich mineral that belongs to the friedelite group of minerals and is not a layer silicate (Kato, 1963). The name rectorite has priority over allevardite for a regular 1: 1 interstratification of …

Clay minerals | Geology Wiki | Fandom

Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations. Clays form flat hexagonal sheets similar to the micas. Clay minerals are common weathering products (including weathering of feldspar) and low temperature hydrothermal alteration products. Clay minerals are very common in fine grained ...

14 - Lecture notes for Clay Mineralogy

Note positions of where the Rectorite super-structure peaks would be (i.e., 001*, 002*...). Some smectite layers are followed by more than one illite layer. Because this is R1 ( i.e ., the reach back or probability of an S following an I is determined by only one layer) there is a random probability for the occurrence of layers beyond one layer.

Montmorillonite - Wikipedia

Montmorillonite is a very soft phyllosilicate group of minerals that form when they precipitate from water solution as microscopic crystals, known as clay.It is named after Montmorillon in France.Montmorillonite, a member of the smectite group, is a 2:1 clay, meaning that it has two tetrahedral sheets of silica sandwiching a central octahedral sheet of alumina.
